FFMPEG change wrong "interlaced" tag back to progressive w/o re-encode

[Gwar]

hey there

I'm having a stack of progressive 29,970 mpeg2 videos which were wrongly converted as interlaced or fake interlaced.
Is there a way to change the scantype of this back to progressive without reencoding the video?

No clue how to do it with FFMpeg, but what should work is:

• extract raw stream with mkvextract (or another tool)
• load raw stream into Restream
• enable "Picture Coding Extension->Frametype progressive"
• disable "Picture Coding Extension->top field first"
• enable "Sequence Extension->Progressive sequence"
• Save file under new.
• exchange video stream in original mkv with the new video stream using mkvmerge gui
